PDFs travel far. Contracts get forwarded, reports get shared beyond the intended audience, ebook previews get saved and redistributed. Watermarking your PDFs puts your name on them - whether that's a visible "CONFIDENTIAL" stamp, a subtle logo, or an invisible tracking mark that proves who leaked the document.
Some tools add watermarks, some remove them, and a few handle both. Here's what's available in 2026.
Add or remove watermarks from images, PDFs, videos, audio, and documents. Batch processing, templates, steganography, and AI-powered removal.
YEB Watermark goes beyond basic "CONFIDENTIAL" stamps. It supports text, logo, pattern, and QR code watermarks with optional AES-256 encryption on the QR payload. Documents up to 100MB and 500 pages, with batch processing for multiple PDFs at once. Plus it handles removal and detection.
Key features:

Best for: Anyone who needs adding, removing, and encrypted tracking for PDF documents

Here's the breakdown:
For most document workflows, you'll eventually need both adding and removing capabilities - adding stamps to outgoing documents and cleaning up watermarks on received PDFs. A tool like YEB Watermark that handles both directions, plus encrypted QR tracking for sensitive documents, keeps everything in one place instead of bouncing between specialized tools.
